The old house carried an assurance, typically 2 Portuguese, that nothing was urgent.

-Acheson, Dean Gooderham
On the US Embassy residence in Lisbon. Sketches from Life of Men I Have Known.

I Tiresias, old man with wrinkled dugs Perceived the scene, and foretold the restö I too awaited the expected guest. He, the young man carbuncular, arrives, A small house agent's clerk, with one bold stare, One of the low on whom assurance sits As a silk hat on a Bradford millionaire.

-Eliot,T(homas) S(tearns)
  The Waste Land, pt.3,'The Fire Sermon'.

All men who live with any degree of serenity live by some assurance of grace.

-Niebuhr, Reinhold
  Reflections on the End of Our Era.

Perhapsthemost sublimeinsights oftheJewishprophets and the Christian gospel is the knowledge that since perfection is love, the apprehension of perfection is at once the means of seeing one's imperfections and the consoling assurance of grace which makes this realization bearable. This ultimate paradox of high religion is not an invention of theologians or priests. It is constantly validated by the most searching experiences of life.

-Niebuhr, Reinhold
  Reflections on the End of an Era.

Philosophy is to be studied, not for the sake of any definite answers to its questions, since no definite answerscan, asa rule, be knowntobetrue, but rather for the sake of the questions themselves; because these questions enlarge our conception of what is possible, enrich our intellectual imagination, and diminish the dogmatic assurance which closes the mind against speculation; but above all because, through the greatness of the universe which philosophy contemplates, the mind also is rendered great, and becomes capable of that union with the universe which constitutes its highest good.

-Russell, Bertrand Arthur William Russell, 3rd Earl
  The Problems of Philosophy, ch.14.

Ifelt my heart strangely warmed.I felt I did trust in Christ, Christ alone for salvation; and an assurance was given methat hehad taken away my sins, even mine, and saved me from the law of sin and death.

-Wesley,John
  Journal entry, 24 May.

Even so for me a vision sanctified The sway of death; long ere my eyes had seen Thy countenanceöthe still rapture of thy mienö When thou, dear Sister! wert become death's bride: No trace of pain or languor could abide That changeöage on thy brow was smoothedöthy cold Wan cheek at once was privileged to unfold A loveliness to living youth denied. Oh! if within me hope should e'er decline, The lamp of faith, lost Friend! too faintly burn; The may that heaven-revealing smile of thine, The bright assurance, visibly return: And let my spirit in that power divine Rejoice, as, through that power, it ceased to mourn.

-Wordsworth,William
